Description

The The invention relates to a headrest for motor vehicle seats with a Retaining element and a network connected to the holding element, wherein the retaining element at least one connection point to the motor vehicle seat having.

It is already a headrest for motor vehicle seats from the DE 27 14 796 C3 known in which the network is associated with one of the backrest, at least on one side an open edge region having and provided with a padding carrier is held under tension. Here, the voltage within the network in different areas of the carrier is designed to be of different heights.

Of the Invention is based on the object, a headrest such train and arrange that a discreet, the driver's field of vision only marginally debilitating Use guaranteed is.

Is solved the task according to the invention by that a first holding element and at least one separately arranged second holding element is provided, wherein the holding element is rod-shaped is. This ensures that the obstructive parts of the Headrest, So the holding elements, essentially vertical, so that they related to the lateral rotation of the head no steady To form a visual obstacle. By the rod-shaped, essentially vertical extending training of the holding part, the driver can be independent of his head height Stop by the holding element. In addition to this safety Aspect of the driver's extended field of view is the feeling of space of the vehicle occupants the transparency of the headrests elevated.

For this it is advantageous that at least provided a third retaining element is, wherein the network between the first holding element and the second holding element and between the third holding element and the second holding element or the first holding element is arranged. Thus, the lateral Extent of headrest extended. This lateral area serves as a so-called headrest ear for support of the head in a resting position.

A additional possibility is according to a further development, that at least a fourth holding element is provided, wherein the Net between the first holding element and the second holding element, between the second holding element and the third holding element and between arranged the first holding element and the fourth holding element is. The trained on both sides extension of the headrest guaranteed a symmetrical shape that is both a right and a left Rest position of the head allows.

Further it is advantageous that the holding element perpendicular to its central axis pivotable and lockable in any position. The pivoting of the holding element is ensured perpendicular to its central axis optimal adjustment of the headrest including the Page ranges in terms of absolute tilt forward and to the rear and in terms of the inclination between the headrest and Headrest ear.

Advantageous it is also this that the holding element and / or the network elastic and / or is plastically formed. The elastic-plastic training guaranteed an optimal impact protection of the head. Here is the plastic Deformation share necessary for some of the kinetic energy is transformed into plastic deformation work. A purely elastic Deformation would the head after the necessary delay again around the same Accelerate amount in the opposite direction.

According to one preferred embodiment of inventive solution in the end provided that the retaining element parallel to its central axis slidably and / or telescopically lockable in any position is. Thus, a height adjustment the headrest and thus ensures an optimal setting for a resting position.

From special meaning is for the present invention that the holding element is a trapezoidal, forming a net-part receiving frame which is around the central axis of the holding element is pivotable. The frame serves as Headrest ear. By the trapezoidal or triangular Training is the driver's field of vision and the sense of space only insignificant with special needs.

in the Connection with the construction and arrangement according to the invention It is advantageous that the holding element, the locking elements has switching control units. The determination of the retaining element is also by twisting around its central axis or by one axial impressions to reach the driver's seat.

Further Advantages and details of the invention are in the claims and explained in the description and shown in the figures. Showing:

2 a 3 D sketch of a headrest with two support elements and triangular ears.

A headrest 1 a motor vehicle seat 2 essentially has four rod-shaped holding elements 3.1 to 3.4 on, in the space between a network 4 or a network part 4.1 . 4.2 is provided. The first holding element 3.1 and the second holding element 3.2 are here in the middle between the third holding element 3.3 and the fourth holding element 3.4 arranged and take the net between them 4 on. According to 1 to the right side is the third holding element 3.3 provided, which together with the second holding element 3.2 the power supply 4.2 spans. Accordingly, on the left outside of the fourth holding element 3.4 provided, which together with the holding element 3.1 the power supply 4.1 spans.

The respective holding element 3.1 to 3.4 is over a connection point 5 with the vehicle seat 2 connected. This connection allows a pivoting of the holding elements 3.1 to 3.4 perpendicular to their partially represented central axes 3.5 . 3.6 forward and sideways towards. Thus, the network can 4 or the network parts 4.1 . 4.2 be set according to a desired driving position or rest position. The network parts 4.1 . 4.2 form together with the third and fourth retaining element 3.3 . 3.4 so-called headrest ears. In addition to the pivoting of the retaining elements 3.1 to 3.4 perpendicular to its central axis 3.5 . 3.6 is also a setting parallel to the central axis 3.5 . 3.6 , ie provided in height.

According to 2 has the first holding element 3.1 and the second holding element 3.2 in each case an outwardly standing first frame part 3.7 or second frame part 3.8 on, which at the upper end of the holding element 3.1 . 3.2 is arranged and with the holding element 3.1 . 3.2 an angle of about 45 °. The respective frame part 3.7 . 3.8 thus forms with the retaining element 3.1 . 3.2 a triangular headrest ear, which according to 2 protrudes to the right or to the left side. The headrest ear thus formed can be about the central axis of the holding elements, not shown 3.1 . 3.2 be pivoted forward or backward, so that a desired rest position is adjustable. Corresponding 1 is also in the embodiment according to 2 between the first holding element 3.1 and the second holding element 3.2 the network 4 arranged.

The network 4 or the network parts 4.1 . 4.2 and the holding elements 3.1 to 3.4 are elastic or elastic-plastic.
